A remote viewing device including a hand-holdable control unit. The control unit supports a display device and a drive assembly. The drive assembly is removably attached to the control unit and provides mechanical power to an insertion tube. A distal end of the insertion tube includes an inspection head for insertion into a structure for imaging the interior of the structure. The insertion tube is removably attached to the drive assembly by a connector assembly, where the connector assembly is operable, when attached, to convey mechanical power from the drive assembly for moving the articulated tip in response to a user input at the control unit, and to convey images from the inspection head to the display device.
